Mapping the Excited State Dynamics of Gas-Phase Spiropyran with Time-Resolved Photoelectron Spectroscopy
We report a femtosecond time-resolved photoelectron spectroscopic study of the excited state dynamics of spiropyran (SP3mt) in the gas phase. Using 266 nm pump and 200 nm probe pulses with an overall instrument response function of 160 fs, the experiment directly resolves the complete early-time evolution following p...
